I attain these objects by the constructions Between and adjacent to thesleeve F and the 7 30 shown in the accompanying drawings. differentialpart I is journaled upon the axle Figure 1 is a plan view of myinvention.

The body- In theconstruction of my gear I employ supporting springsarepreferablyattached by the usual vehicle-wheels A, A A and A, means of a pivotedpiece L, Fig. 4, and either the guiding-axle B, and reaches or side barsattached to the corner-bearings or their con- 45 C and D. The reachesare preferably connections.

nected to the guiding-axle B, as shown in The motor P is directly orrigidly connect- Fig. 5, in which they are provided with a reed to L andprovided with journals P and P duced extension O, which passes throughthe in which a driving-shaft P is journaled, as soft-rubber washers Oand metal ring O shown by the dotted lines in Fig. 2, and is providedwith a pinion P, which meshes with a gear K. While I have shown anelectric motor, yet another power might be utilized, or instead of themotor a framework only could be provided and the shaft P receive itspower from another source. The reach C, Fig. 4, is pivoted to the motorP at its forward end and has an extension 0', which passes under themotor and is connected to L by means of springs G and This reach could,however, be rigidly connected to the forward end of the motor or on L,or the pivotal connection could be at the rear and the springs in frontand accomplish the same results. Thus the motor is preferablyspring-supported and permitted to vibrate around the driving-axle byreason of the corner-bearings. The motor pivotal or supporting pointsact also as body-supporting bearings, which are preferably fitted withantifriction-bearings, as shown. The flexible sidebar' connections tothe guiding-axle and the pivotal connections at the driving-axle permitthe desired flexibility.

In Fig. 4 I have shown by dotted lines the spring G which can beattached to the bodysill, and thereby dispense with the use of theside-bar support for the motor.

In Figs. 6 and 7 the body-supporting springs L and M are rigidlyconnected to the cornerbearings or motorpivot, thereby holdingthe motorin working position without the use of side bars. To assist insupporting and holding down the motor, cross-springs L and L may beprovided. The corner-bearings are shown connected together by a bar orbrace 0 the axle B being exposed and the motor bolted directly to thebar.

Referring again to Figs. 2 and 4, the gear K and pinion I are protectedby the gearcase Q, which is preferably formed in halves, as indicated inFig. 2, and is held together and in position by bolts Q, by means ofarms Q and the journal P. This gear-cover is preferably made to coveronly the periphery of the gear, as shown in Figs. 2 and 4.

The brake-leverRacts u pon the brake-band J through a bell-crank J andshaft J The motor acts as a support for the shaft J, which passesthrough the motor and between its field-pieces. Thus no additionalfixtures are necessary for the brake mechanism, and all the workingparts are formed in such a manner as to prevent displacement.

The motor-supporting reach might be located near the center of the gearand the other dispensed with or numerous other minor changes madewithout departing from the scope of the invention.
